This video clip will give us a whole new perspective on our ideas of dimension and symmetry as it demonstrates the significance of both an "observed object" and "its context." It starts with a simple question which is "how do we recognize the existence of that dot?” Besides the factors of a dot and its perceptual process, there's one more factor. That is the area surrounding our dot. For instance, a black dot cannot be visible with the surrounding area in black. That is, in order for a black dot to be visible, it needs to be surrounded by any other color but black. With this new perspective, the clip develops a pattern into a diagram called "Dimension Development Diagram."
